HostsEditor is small useful utility that manages IP name mapping. So you could specify an IP and a matching name and it will be set up within your system.
For example, if your e-mail account has long URL-name match its IP to the 'mail' word. Just then you may see your mails by typing 'mail' into web-browser!
Also it works for FTP, Ping, Traceroute, ...
If you don't know the IP, the application will determine IP itself.
Help is available by 'F1'.
